Winter Storm Quinn Smothers the West in Heavy Snow, but Will Finally Kick East to the Plains, Midwest and Northeast Into Next Week
Winter Storm Quinn will continue to pound the Mountain West into the weekend and will also spread snow and strong winds through the northern Plains, upper Midwest and Northeast into next week.
A deep southward dip in the jet stream will begin to shift east was through the central Rockies this weekend, then into the Plains states Sunday and into the upper Midwest by Monday, where blizzard conditions could develop in some areas. Eventually, Quinn could spread at least some snowfall into the Northeast by the middle portion of next week.
Snow is falling from parts of eastern Montana southwestward to southern Idaho, northern Utah, western Wyoming, Nevada, Oregon and the mountains of California, as of Saturday evening.
Parts of Idaho, California and Nevada have all received more than three feet of snow so far, with more on the way in California and Nevada.
Friday night into early Saturday, snow was falling in low elevations of northern California, leading to widespread road impacts. Roadway concerns will persist through Saturday.
Heavy rainfall has also been reported with this system, with more than 9 inches recorded at Chalk Peak in Big Sur, as of Friday night.
Winter storm warnings and winter weather advisories have been issued by the National Weather Service from parts of the northern and central Rockies and the northern high Plains westward to California and Utah as well as a small part northern Arizona. A winter storm warning is now in effect for the Salt Lake City metro area into Sunday evening.
Winter storm watches have also been hoisted for much of the northern Plains, from eastern Montana and northeast Wyoming into the Dakotas, northern Nebraska, northern Minnesota and northwestern Wisconsin. A winter storm watch is now in effect for the Minneapolis metro area. Difficult travel conditions are possible this weekend into next week.
Winter Storm Quinn began as a slow-moving, but deep trough dropped southward from the Gulf of Alaska on Feb. 28 toward the Pacific Northwest. A cold front associated with Quinn swept through the West Coast from Washington to central California on Mar. 1 with a reinforcement of moisture and cold air.
